I'm stuck with understanding the following sentence from Effective Modern C++: 42 Specific Ways to Improve Your Use of C++11 and C++14
yes, the syntax looks toxic, but knowing it will score you mondo points with those few souls who care.
What are these mysterious "mondo points"? I googled it and it relates to shoe size which seems kind of weird.
Do I understand correctly that these points are represented by souls? I also found that there is a phrasal verb "score with" which means to please somebody or someone. So in this case, knowing will score with (please) few souls and you is now irrelevant?
